Lipopolysaccharide binding protein as a marker of inflammation in synovial fluid of patients with arthritis: correlation with interleukin 6 and C-reactive protein.

OBJECTIVE. To determine levels of lipopolysaccharide binding protein (LBP) in serum and in synovial fluid (SF) of patients presenting with various articular disorders [degenerative arthritis, rheumatoid arthritis (RA), reactive arthritis (ReA)] and to correlate these levels with C-reactive protein (CRP) and interleukin 6 (IL-6), 2 markers of the acute phase response. METHODS. LBP was measured by a radioimmunoassay made up of lipopolysaccharide (LPS) to capture LBP and radiolabelled anti-LBP antibodies to detect LBP. LBP was also measured for its ability to present fluorescein isothiocyanate LPS (FITC-LPS) to human monocytes. CRP was measured by nephelometry and IL-6 bioassay. RESULTS. Levels of LBP in serum and in SF were significantly higher in patients with RA and ReA than in the control group of degenerative arthropathies. In the latter group, LBP values were similar to those found in controls. Serum LBP values correlated positively with SF LBP values. LBP values also correlated with CRP and IL-6 levels measured in SF. Functionally, LBP was found to be active and able to present LPS to monocytes, resulting in tumor necrosis factor-alpha (TNF-alpha) release upon LPS challenge. CONCLUSION. These in vitro data support the observation that LBP could play a major role in local joint disorders. Our results also strengthen the view that LBP may be a new marker of synovial inflammation.[1]
